XPath Search

This feature is only supported in the Ultimate edition.

This new feature is the XML-aware counterpart to IntelliJ IDEA built-in functions Find in Path and Search Structurally. It allows you to find occurrences of certain XPath expressions in all XML files in a specific scope. It is available through Edit | Find | Find by XPath... on the main menu.

The scope that can be chosen is either the full project scope, a specific module or a simple directory. There's also the ability to use custom scopes, but this is somewhat limited as it will only scan XML files inside source-folders.

This dialog provides the same functionality regarding completion, error checking, and intentions as described in Evaluate Expression.
